File Information

In a number of vibration applications, systems under study are slightly non-linear. Cascade of Hammerstein models conveniently allows one to describe such systems.
The Hammerstein Toolbox provides a simple method based on a phase property of exponential sine sweeps
to estimate the structural elements (Kernels) of such a model from only one measured response of the system.
